APPARATUS FOR HEATING AIR IBY STEAM.

SPECIFICATION forming part of Letters Patent No. 258,159, dated May 16, 1882.

Application filed December 7, 1881. (No model.) I v To all whom it may concern .Be it known that I, JAMES P. WOOD, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Heating Air by Steam in Vacuo, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a partial front view and vertical section of the heating apparatus embodying my invention. Fig. 2 is a transverse vertical section in line as m, Fig. 1. Fig. 3 is a trans verse vertical section in line 3/ y, Fig. 1. Fig. 4 is an enlarged vertical section of a detached part.

Similar letters of reference indicate corresponding parts in the several figures.

. My invention consists, first, of a combustion-chamber, in combination with a heatingchamber arranged at the side thereof, a partitlon which divides said heating'chamber into a nearer section and afarther section,and two or more closed pipes extending from said combastion-chamber through or into each section of the heatingchamber, and an indepei dent air-inletand air-exit for each section of said chamber; second, of two plates having a packing interposed between them, and having openings to receive pipcs,in combination with said pipes, the combustion-chamber, and the heating-chamber, all substantially as hereinafter set forth.

Referringto the drawings, Arepresents heating-tubes, each containing a small quantityof liquid in a vacuum, as shown in theLetters Patent,No. 181,125, granted to 'I. Angell, August 15,1876; butother forms of tubes may be used, said tubes being supported on the walls a, which surround the combustion-chamber B, the inner ends of the tubes projectinginto said chamber and on the bridges O, which divide ments, so as to direct the foul air thereof to.

the space (Z, and the exit f discharging such air into the atmosphere, by which provision the apartments may be nicely and conveniently ventilated.

F represents plates, which are perforated for the passage ofthe tubes A, and arranged vertically in pairs against theoutside of the firebrick wall E, a filling, g, of fire-proof cement or other materialbeing placed between the two plates, thus forming a tight joint between the combustion-chamber and the tubes, and preventing the escape of gases into the hot-air chambers, the perforated plates also serving to locate the tubes their proper spaces apart.

On the front plate, a, of the apparatus is a door, G, the frame G whereof is removably fitted to said plate above the furnace-door proper. For this purpose the back of the frame is provided with inwardly and downwardly projecting hook-shaped lugs h, which enter openings lain said plate surrounding the'opening proper in said plate.

It will be seen that the, door G may be used as a damper; but when access is required to the ends of the pipes within the combustionchamber for cleansing the same, or other purposes, the frame G is raised clear of the openings in which the logs are fitted, and thus the frame with the door is bodily removed from the plate, thus providing a large opening for the inserting of the cleansing tools or appliances. In order to restore the door, the frame is presented to the opening in the plate, and the lugs h are inserted in the respective openings, whereby the-frarne is again located and secured in position.

The upright bridge 0 in the hot-air chamber, according to the direction of the wind, so

that some of the outlets or fines, and consequently the apartments to which they lead, are

not supplied with heat. This defect is remedied by my constructionviz., the employment of the bridge 0, each section of the hotair chamber formed by the bridge having its own air-supply and heat-discharge independent of the other section or sections, and each section is heated by the tubes A, so that there is a reliable and uniform distribution of hot air from the apparatus, and each apartment or locality is unfailingly supplied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-=-- 1. The combustion-chamber B, in combination with the heating-chamber D, arranged at the side thereof, the partition 0, which divides said heating-chamber into a nearer section and a farther section, the closed pipes A, extending from said combustion-chamber through the first section andinto the other section of the heating-chamber, and an independent air-inlet and air-exit for each section of said chamber, substantially as set forth.

2. Two plates, F, having packing g interposed between them, and having openings to receive pipes A, in combination with said pipes, the combustion chamber, and the heatingchamber, substantially as set forth.
